20140085743 | REAL TIME MRA ESTIMATION AND CORRECTION USING ADC SAMPLES - Methods and systems for estimating MRA for a hard disk drive are described. The methods and systems described herein provide for real time estimating and correcting magneto-resistive head asymmetry (MRA) in a hard disk drive using analog-to-digital convertor (ADC) samples or counts. Generally, ADC outputs may be obtained by injecting MRA at known values, where an estimated MRA may be derived in real time by applying an equation using particular ADC output values. Once an estimated MRA is obtained, MRA correction may be performed when the estimated MRA is larger than a threshold value, such as by adjusting a channel MRA compensation coefficient. | 03-27-2014 |
20140095961 | LAYERED DECODER ENHANCEMENT FOR RETAINED SECTOR REPROCESSING - A system is described for recovering data from a number of sectors, such as the sectors of a hard disk drive (HDD) disk platter, and so forth. The system receives data from the sectors via a read channel and uses a layered data decoder to recover data from the sectors. A memory is coupled with the processor and configured to retain data received from one or more of the sectors, e.g., in retained sector reprocessing (RSR) embodiments. The system is configured to update messages in different circulant layers of the data decoder's parity-check matrix. The system uses one message update order in a processing iteration, and different message update orders in subsequent reprocessing iterations. In some embodiments, layer reordering is used for RSR. In some embodiments, circulant reordering is used for RSR. | 04-03-2014 |
